Definitions
- Flowable formulations of pesticides provide a method for applying water insoluble pesticides in an aqueous spray that avoids the handling of solid formulations such as wettable powders and granules.
- Aqueous based flowable compositions further avoid the use of organic solvent based flowables and emulsifiable concentrate compositions.
- the present invention is novel aqueous flowable compositions comprising 10% to 40% on a weight to volume basis of a finely ground particulate pesticide or mixture of pesticides suspended in an aqueous solution containing 5 to 40% by weight of a surfactant; 1.0% to 8.0% on a weight to volume basis of a wetting and/or dispersing agent and optionally containing 0.5% to 1.5% of an antifoam agent and 1% to 10% of an antifreezing agent.
- Stable aqueous flowable concentrates of solid pesticides may be prepared without the use of additional thickening agents such as clays and soluble gums, which are normally used to prevent or slow settling, by utilizing aqueous solutions containing 5% to 40% by weight of surfactants which as 25% aqueous solutions have kinematic viscosities of about 5 to about 100 centistokes as the vehicle for the flowable composition.
- Surfactants giving kinematic viscosities in the above approximate range permit the use of sufficient quantities of said surfactants to obtain aqueous flowable concentrate compositions containing on a weight to volume basis 10% to 40% of solid finely ground pesticides, 1.0% to 8.0% of wetting dispersing agents and optionally 0.5% to 2.0% of antifoam agents, and 1% to 10% antifreezing agents such as glycols and alcohols, having viscosities of from 600 to 6,000 centipoises and preferably 1,000 to 3,500 centipoises as measured by a Brookfield viscometer, with a number 2 spindle at 6 rpm at 20 o C, which resist settling of the solid components and do not gel.
- the kinematic viscosities of these surfactants measured as a 25% aqueous solution, allows the incorporation of high levels of surfactants in the final aqueous flowable pesticidal compositions, without causing them to become too viscous to process and use easily.
- the incorporation of high levels of surfactant provides the additional benefit that surfactants need not be incorporated during dilution of the flowable composition in a spray tank prior to application, making the compositions of this invention easier and safer to apply.
- Surfactants suitable for use in compositions of the invention include polyoxyethylene alkyl phenols, polyoxyethylene styryl phenyl ether salts, polyoxyethylene fatty acids, polyoxyethylene alcohols and the like.
- Preferred surfactants for use in compositions of this invention are non-ionic, with the polyoxyethylene nonyl phenols containing 9 to 13 moles of ethoxylation and mixtures thereof being most preferred.
- the pesticides that may be used in these stable concentrated flowables must be solids having essentially no significant water solubility (i.e., less than about 1.0 g/100 cc H 2 0 at ambient temperature) and a particle size less than 20 ⁇ , usually in the range of 0.5 to 20 p. Preferably such particles will range in size from 0.5 p to 5 ⁇ .
- Pesticides e.g., insecticides, fungicides, vi- ricides, acaricides, herbicides, bactericides, and the like, having the above specifications may be used in the aqueous flowable concentrates of this invention.
- a representative example of a presently available pesticide which may be used in this invention is the recently introduced imidazolin-2-yl benzoate herbicide which is an isomeric mixture of methyl 6-(4-isopropyl-4-methyl-5-oxo-2-imidazo- lin-2-yl)-m-toluate and methyl 2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl-p-toluate.
- Stable aqueous flowable concentrates containing high concentrations i.e. 20% to 35% on a weight to volume basis of this herbicide may be readily prepared by milling an aqueous slurry containing 30% to 45% by weight of the herbicide, 2.0% to 4.0% by weight of a dispersing and/or wetting agent optionally containing 0.5 to 2.0% of an antifoam agent to the appropriate average particle size range of 0.5 to 20.0 microns and preferably less than 5 microns.
- the aqueous flowable concentrate composition is then prepared by adding any additionally desired quantities of wetting and/or dispersing agents, and antifoam agents or antifreezing agents; and sufficient required water to total 100% of the final composition, followed by the addition to the agitated aqueous slurry, of 5% to 35% of a surfactant having a kinematic viscosity of about 5 to about 100 centistokes.
